I'm using (for amy.ac a math tutoring platform) Firebase now since about 10 month and I'm quite happy with it (now). After about ~3 month I became pretty tired of it since I came from a SQL background and I had no way of dealing with fancy queries. At this stage I almost switched to Deepstream (Sorry deepstream but non of your examples worked, so no Deepstream for me. Also I need todo my own load balancing, etc.). Why I still use firebase has 2 major reasons. 1) Cloud Functions 2) Using Firebase-DB as my model and never query anythings from firebase. 3) I really don't want to touch docker/aws/load balancing/etc. In my case, the client simply listens/writes to a particular model (DB-path). A cloud function will wake up, manipulate the model and falls a sleep. That pretty much means, every view-model a user can see is pre-calculated and stored in the DB.
